Stone cornices have been a defining architectural feature for centuries, adding refinement and visual interest to both residential and commercial buildings. These horizontal decorative elements project from the roofline or upper wall, creating shadow lines and breaking up the vertical plane of a facade. When executed in natural stone, cornices convey a sense of permanence, craftsmanship, and classical elegance that enhances the overall character of a property.
But stone cornices come with substantial challenges that often make them impractical. The material is extremely heavy, requiring extensive structural support to bear the weight safely. Fabrication involves skilled stonemasons, lengthy production times, and high labor costs. Shipping costs are significant due to weight, and installation demands specialized equipment, multiple workers, and careful planning to avoid accidents or damage. For many projects, these factors push stone cornices beyond budget or timeline constraints.
At Patterson Whittaker Architectural Profiles, we manufacture stone cornice alternatives using cement-coated architectural EPS that replicates the appearance and detailing of natural stone without the logistical and financial burdens. Our products are used throughout the United States and Canada by architects, contractors, and builders who want the visual impact of stone cornices but need a solution that is lighter, more affordable, faster to produce, and easier to install.
If you are considering stone cornices for your project but want to explore a modern alternative that delivers authentic results, Patterson Whittaker Architectural Profiles is available to provide additional information.

About Stone Cornices and Their Structural Challenges
Stone cornices serve both functional and decorative purposes in architecture. Functionally, they can help direct water away from the building facade, protecting walls and foundations from moisture infiltration. Decoratively, they add depth, proportion, and elegance to a building’s profile, often serving as a transitional element between the wall and the roofline.
Traditional stone cornices are crafted from limestone, granite, marble, or sandstone, with each stone type offering distinct visual characteristics. The material is carved to create profiles ranging from simple beveled edges to elaborate dentil moldings, modillions, and ornamental brackets. When executed properly, stone cornices are durable and long-lasting, capable of withstanding decades of weathering without significant deterioration.
However, working with stone cornices introduces several practical challenges:
- The weight of natural stone creates structural concerns – walls must be reinforced to support the load, and attachment systems must be engineered to prevent failure or sagging over time.
- Fabrication is expensive because it requires skilled labor, specialized equipment, and careful attention to detail to achieve consistent profiles and joinery. Shipping costs are high due to weight, and there’s a risk of damage during transit, especially with delicate carved details.
- Installation is complex and dangerous, typically requiring scaffolding, lifts, multiple workers, and precise measurements to ensure proper alignment and secure attachment. Any mistakes during installation can compromise both safety and aesthetics.
These obstacles make stone cornices cost-prohibitive for many residential and commercial projects. Even when budgets allow, the extended timeline and complexity can create scheduling conflicts that delay completion.
Cement-Coated Architectural EPS – A Stone Cornice Alternative
Our stone cornice alternatives are manufactured using a reinforced EPS core that is coated with a proprietary blend of polymers and cementitious materials. This process creates a cornice that captures the appearance, texture, and shadow lines of natural stone while eliminating the problems associated with weight, cost, and installation difficulty.
Patterson Whittaker stone cornices offer the following advantages:
- Lightweight Design – Dramatically reduces structural requirements and makes handling safer for installers
- Lower Material Costs – Substantially less expensive to produce than quarried and carved stone
- Faster Lead Times – Shorter production schedules compared to traditional stone fabrication
- Reduced Shipping Costs – Lightweight construction means lower freight expenses, even for large or complex profiles
- Simplified Installation – Can often be installed by one or two workers without heavy equipment or extensive scaffolding
- Weather Resistance – Engineered to withstand freeze/thaw cycles, UV exposure, and moisture without cracking or deteriorating
- Consistent Quality – Manufacturing process ensures uniform profiles and dimensions across all pieces
- Eco-Friendly Materials – Made with recyclable components and produces less waste during production and installation
Our cornices have been tested under extreme environmental conditions and maintain their structural integrity and appearance over time. The cement-based coating provides a durable, impact-resistant surface that resists moisture penetration and environmental wear.
Available Cornice Profiles and Finishes
Patterson Whittaker manufactures stone cornices in a wide range of profiles, from simple classical designs to elaborate decorative moldings. Whether you’re working on a traditional restoration project that requires historically accurate detailing or a contemporary design that calls for clean, modern lines, our manufacturing process allows for flexibility in both style and scale.
We can replicate the appearance of various natural stones to match your project’s aesthetic and architectural context:
- Limestone – Popular for its refined appearance and warm coloring, but vulnerable to acid rain and freeze/thaw damage
- Granite – Prized for its strength and polished finish, but extremely heavy and costly to fabricate into detailed profiles
- Marble – Valued for its elegance and distinctive veining, but expensive, fragile, and prone to staining from environmental exposure
- Sandstone – Appreciated for its earthy tones and natural texture, but softer and more susceptible to weathering and erosion
- Travertine – Known for its unique pitted surface, but porous and requires regular sealing to prevent water penetration
Our finishing process can mimic the look and feel of these materials, allowing you to achieve the desired visual effect without the drawbacks of working with actual stone. Cornices can be smooth, textured, or detailed with carved elements such as dentils, egg-and-dart moldings, or modillions, depending on the architectural requirements.
Applications for Stone Cornice Alternatives
Because our cornices are engineered to replicate both the appearance and performance of natural stone, they can be used in nearly any architectural application where stone cornices would traditionally be specified. Common uses include:
- Residential exterior cornices that define the roofline and add visual weight to the facade.
- Commercial building cornices that provide a finished appearance that enhances curb appeal and property value.
- Restoration projects that require matching existing historic stonework benefit from our ability to replicate specific profiles and finishes.
- Interior cornices in high-end residential and commercial spaces that create a sense of grandeur without the structural concerns of heavy stone.
- Decorative cornices for columns, pilasters, and entryways add architectural detail and visual interest to otherwise plain surfaces.
In addition to cornices, our system can also replace other stone architectural elements such as columns, quoins, trim, arches, and wall panels. This allows architects and contractors to maintain design consistency throughout a project while using a single material system that reduces complexity and cost.
Why Architects and Contractors Choose Patterson Whittaker
Natural stone will always have a place in architecture, but for most projects, the cost, weight, and installation requirements make it less practical. Patterson Whittaker Architectural Profiles provides an alternative that delivers the same aesthetic results while addressing these concerns.
Our cement-coated EPS cornices give architects greater design freedom because the material can be produced in custom profiles and lengths without the limitations of working with quarried stone. Contractors benefit from reduced labor demands, faster installation times, and fewer safety concerns on the job site. Property owners get a final product that looks and performs like stone but requires less maintenance and holds up better over time in varying weather conditions.
The material is also more forgiving during installation. Unlike natural stone, which can crack or chip if mishandled, our cornices are resilient and can tolerate normal construction site conditions. If field adjustments are needed, the material can be cut and shaped on-site without specialized masonry tools.
